will mason commented on GROOVY-8339:
------------------------------------

This error occurs with java *10* (*18.03*) on Groovy 2.4.12 and *2.4.14* which seems to be
the current Release/Production version.  JDK 9 is done now.

This problem appears to have effects.  Plugins and tests that depend on Groovy can find they
don't like the problem.
